GEORGE E. AMES, OF SAN FRANCISCO, CALIFORNIA.

ROCK-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 400,157', dated March 26, 1889.

Application filed August 8, 1.888. Serial No. 282,257. (No model.)

To all 207mm, t 711,601/ concern.'

rBe it known that I, GEORGE E. AMES, of the city and county of San Francisco, State of California, have invented an Improvement in Rock-Crushers; and I 'hereby declare the foly lowing to be a full, clear, and exact description of the same.

My invention relates to that class of rockcrushers in which amovable or vibrating jaw operates against an opposing fixed jaw, the rock being crushed between the two jaws; and my invention consists in the novel (letails of construction and arrangement, which I shall hereinafter fully describe and claim.

The object of my invention is to increase the capacity and strength of the machine, to reduce its weight, and to provide simple and reliable means for eifecting the several adj ustments.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure lis a side elevation of the crusher. Fig. 2 is a vertical section of the same. Fig. 3 is a plan.

A are the frame-castings of the machine, connected together by longitudinal bolts B. In one end of themachine is secured the fixed jaw C, opposing which is the movable or vibrating jaw D, which is pivotcd or journaled at E at its upper end.

F is the drive-shaft of the machine, having fly-wheels f and the usual fast and loose pulleys .f-

G is an ecoentricont-hc shaft F, from which depends the connecting-rod ll.

I is an arm having its rear end seated in the forward side of. the connecting-rod II and its forward end seated in the back of the movable jaw.

J is an arm having its forward end seated in the back of the connecting-rod II and its rear end seated in the transverse support K, consisting of a bar which is mounted and adapted to be adjusted upon the projecting rear ends of the bolts B back of the rearcasting of the frame. Nuts l) are Iitted on the bolts at their rear ends, said nuts being set u p against the back of the support to effect it-s proper adjustment.

Ii is the take-np rod, the forward end of which is connected with the base of the movmotion of the eccentric, it raises the forward arm, I, in its bearings and causes the movable jaw to vibrate on its pivotal center, thereby effecting the crushing of the rock between the jaws. move the support K forward the wear on all the arms is properly taken up and the opening between the jaws is adjusted with respect to its capacity. The working strain is takenby the bolts B.

In the face of the fixed jaw O is fitted the wearing-plate c, and in the face of the movable jaw I) is fitted the wearing-plate d. These are held in place by means of keys c CZ', as shown, which enables them to be easily replaced when necessary. The wear on the journal E of the movable jaw is taken up by means of a sliding gib, iT, which is tted in a recess in the head of the jaw and presses against the journal, said gib being set up to place by means of the set-screw n. 'lhe bearings of the arms I and .I are formed of steel blocks O, properly let into their seats and held in place bymcansof set-screws o. rIhese blocks receive all the wear, and can be readily taken out and replaced when necessary. The bearings of the arms and other journals and. joints of the machine are kept properly lubricated by means of the pipes P, the lowerl ends of which are jitted into the oil-holes below, and their upper ends extend above the frame of the machine, -so as to be easily reached for the purpose of pouring the oil into them. rlhe connecting-rod H is fitted to the eccentric by means of the cap-piece 71 which embraces the top of the eccentric and is secured to the rod by means of the bolts 71,. This construction provides for the easy adjustment and substitution of the rod. The take-up rod L is secured by a link, l., to the eyebolt Q, which is let into the base of the By setting up the nuts l) so as to IOO strain, said bolts havingshoulders b', project? ing rear ends, nuts lf2, the sliding Support K, mounted on the projecting rear ends of the bolts outside of the frame-eastinge, the nuts for moving' said Support; K, and the arm ,l between the conneeting--rod and the snliporilx, Substantially as herein deseril'ied.

In witness whereof I have hereunto Setnly hand.
